Patent DE-3730273-A1 (DE)
Title: Device for extracting smoke and pollutants
Inventor: FUCHS HARALD
IPC: F16L41/18
Filed: 1987-09-09
Abstract: Devices known hitherto use, for extraction, extraction hoods which are capable of extracting the air over the entire workplace covered by the working means. In this case, however, relatively large air volumes have to be moved, requiring a corresponding efficiency of the filter system and of the suction fan. The novel device, on the other hand, uses an extraction nozzle which moves with the working means. The extraction nozzle is connected to an orifice which is movable along a suction opening of a suction channel in such a manner that the subatmospheric pressure prevailing in the interior of the suction channel is transmitted, via the orifice, to the extraction nozzle. Sealing means are also provided which continuously seal the suction opening at the points not covered by the orifice. The device is suitable in particular for a robot welding system.
Patent DE-3733914-A1 (DE)
Title: Welding device for joining plastic profiles
Inventor: PUTSCHER JOHANN DIPL ING
IPC: B29C65/20
Filed: 1987-10-07
Abstract: A welding device for producing corner joins in plastic profiles comprises two movably mounted mould halves the top sides of which are provided with a groove to receive the profiles and which mould halves have end faces which are directed towards one another and are inclined with respect to the direction of the groove at an angle corresponding to half the angle of the corner joint. Covers attached to the mould halves cover the groove in the closed state. Cutting and welding devices serve for cutting off the profile ends projecting at the end faces of the mould halves when the mould halves are moved apart and for fusing the cut edges which are pressed against one another by movement of the end faces when the mould halves are closed and welding them to one another. To avoid a deformation of the profiles during the cutting operation, stop slides which are slidable in the direction of the groove are arranged in the covers or in the mould halves, above or below the cross-sectional delimitation of the groove, and can be advanced, by means of pretensioning devices, beyond the end faces when the latter are distant from one another and, during closing of the mould halves, can be slid into the cover or into the mould half.

Inventor: KALVERKAMP KLEMENS DIPL ING
IPC: A01D41/14
Filed: 1988-02-03
Abstract: In the known combine harvesters, the reaping and/or pick-up headers are wider than the actual working machine and therefore, for road transport, have to be either removed or folded in such a way that movement by road is possible without difficulty. At the same time, the driver's field of vision is often restricted and the individual reaping and/or pick-up headers are of complicated design. To avoid the disadvantages of the known arrangement, it is proposed that only one header part (B) be pivotable on the other header part (A) about an axis (2) pointing in the direction of travel and can be laid onto this, and the two header parts can then be displaced transversely relative to the longitudinal axis of the harvester. <IMAGE>

Patent DE-3810141-A1 (DE)
Title: Apparatus for producing safety knots
Inventor: SCHUMANN FRANK DR
IPC: B65H69/04
Filed: 1988-03-25
Abstract: The invention relates to the production of safety knots in book-binding, for binding individual layers together for insert brochures, multi-layer brochures and books. A horn-shaped element (winding horn) and a hook-like element (winding hook) are fixed opposite to each other on a periodically rotating or vibrating machine element, hereinafter referred to as a knotting head. Thread loop elements are introduced from a stitching needle above the material to be processed and are received on the winding horn. By rotation of the knotting head, these thread elements are stretched in loop form between the winding horn and winding lever. The apparatus includes a single-armed winding lever which accepts the thread loops from the winding horn. Furthermore, a gripper is provided in a known manner for the subsequent taking-over of the thread loops and pre-forming of the knot, the angled lever inverting the sides of the thread loop, tensioned between the winding horn and winding lever, on both sides of the pieces of thread between the needle perforation and the winding hook. The latter working step is also reversible. The proposed solution can dispense with additional thread guide elements. The thread is directly taken over by the knotting head. A substantial simplification of the stitching process is thus achieved.   <IMAGE>

Filed: 1988-07-22
Abstract: To abolish the multiplicity of electrical conductors, wires, double wires or cables, previously necessary for the illumination of christmas trees, decorations and artwork by means of electrical connections, the power supply of light-emitting elements is carried out without any electrical connection. The energy source consists of an RF transmitter which emits a constant frequency (e.g. 27 MHz) with a sufficient power (e.g. 2 watts) continuously or in a pulsed manner or of an infrared radiator, a laser, or a battery of electroluminescent diodes, connected in parallel and in series, which emit infrared light continuously or in a pulsed manner. The light-emitting elements are directly connected to an electrical resonant circuit (tuned circuit) which consists of an inductance and a capacitance (e.g. coil and capacitor). The light-emitting elements can be formed from electroluminescent elements (LE), electroluminescent diodes (LED), vacuum fluorescent diodes (VFE), glow lamps or incandescent lamps of different colours and shapes and can be used to illuminate christmas trees, decorations and artwork.

Abstract: Situated inside a portable measuring head (A) is the laser light source (FL), preferably a directly modulated, diode-pumped neodymium/YAG laser. Its laser beam (f1) is directed without optical waveguides using a scanner device (5) and a dual optical system (6) onto the scanning zone of the material sample (B) to be inspected. The irradiated measuring track is, for example, meander-shaped with beam deflection in the x and y direction. The dual optical system (6) transmits the IR light signals (- DELTA  f3) emitted by the sample (B). These are focussed on an IR detector (8) via the scanner device (5) and a coupling mirror (4b) in the form of a dichroic mirror which reflects the laser beams (f1) in one direction and acts as a transparent window in relation to the IR light signals (- DELTA  f3) in the other direction, and via an IR optical system (7). The IR detector (8) converts the IR light signals (- DELTA  f3) into corresponding electrical signals. The measuring head (A) is connected via a flexible electrical connecting cable to an electronic image generating unit from which the electrical signals for controlling the laser (FL) and guiding the beam originate. 
<??>The invention also relates to a number of advantageous uses of the method and also to a device for carrying it out.
